SELTZER J BWM MW' ATTORNEYSUnited States Patent 3,339,548 DIAPER CONTOURED BY SHRINKING Norman L.Seltzer, Princeton, N.J., assignor to The Kendall Company, Boston, Mass,a corporation of Massachusetts Filed Apr. 27, 1964, Ser. No. 362,785 16Claims. (Cl. 128284) The present invention relates to diapers and moreparticularly to diapers which are contoured along side edges thereof toprovide a better and more comfortable fit for a wearer. Still moreparticularly, the present invention relates to such contour diaperswhich have substantial lateral stretchability and recoverability.

Diapers have been formed for many years from sheets of fabric materialof either single layer or multi-layer construction by folding thesesheets into a rectangular configuration. In certain diapers, normallyreferred to as prefold diapers and which are becoming increasinglypopular, the folded fabric is secured in the rectangular configurationby stitching the layers thereof together. Such conventional diapers arerelatively inexpensive to manufacture, have high absorptive capacity,easy cleanability and various other well-known desirablecharacteristics.

However, when such conventional diapers are applied to infants, themedial portions thereof lie between the infants legs and the Width ofthe diaper material in these medial portions tends to spread the legs ofthe infants into unnatural positions. Also, such conventional diapersbecome greatly wrinkled or puckered in their medial portions when beingworn, which wrinkles or puckers are a source of irritation to thewearers and are subject to excessive wear.

Various attempts have been made to solve the problems encountered in theuse of such conventional diapers, but all of these attempts have beenunsuccessful. One example of such an attempt is a contour diaper formedby cutting, folding and stitching the diaper fabric in such a mannerthat the side edge portions of the diaper have a concave configuration.This contour diaper, however, has several deficiencies, one of which isthe irritation of the skin of the wearer by the sewn cut edges definingthe contou-r areas. Another deficiency of this prior contour diaper isthat the cutting, folding and sewing thereof is quite time consuming andlaborious and, therefore, this diaper is considerably more expensive tomanufacture than corresponding non-contour diapers.

Another example of a prior contour diaper is shown in United StatesPatent No. 2,866,459 to Sobelson and comprises a folded diaper which hastransversely extending elastic stitching the medial portion thereof,which stitching was initially placed therein in a stretched condition,and then permitted to relax and draw in the side edges of the medialportion to impart a concve configuration thereto. However, this drawingin of the diaper material by the elastic stitching results inconsiderable wrinkling of the diaper fabric which is undesirable sinceit irritates the wearer and is subject to excessive wear. Also, theelastic stitching becomes brittle and frequently breaks after only a fewlaunderings of the diaper. Further, this elastic stitching is relativelyexpensive and the stitching operation is also time consuming andlaborious and, hence, the resulting diaper is expensive.

With the foregoing in mind, it is an object of the present invention toprovide a novel contour diaper having the desirable characteristics ofconventional non-contour diapers of corresponding layer construction andwherein the aforementioned deficiencies of prior contour diapers areobviated.

Another object of the present invention is to provide a diaper which isso constructed that when the same is washed or laundered, as is usuallydone with new diapers A further object of the present invention is toprovide a novel diaper of the character described which has substantialstretchability and recoverability laterally thereof for furtherenhancing the fit of the diaper on a wearer.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawings, in which- FIGURE 1 is a plan view of a diaperaccording to the present invention in unfolded condition;

FIGURE 2 is a somewhat schematic sectional view taken substantiallyalong line 22 in FIGURE 1;

FIGURE 3 is a plan view of the diaper in folded condition beforeshrinkage thereof;

FIGURE 4 is a plan view of the diaper shown in FIG- URE 3 after beingshrunk;

FIGURE 5 is a plan view of another form of dia-per in unfolded conditionand incorporating the features of the present invention;

FIGURE 6 is a perspective view of the diaper shown in FIGURE 5 in foldedcondition and before shrinkage ing longitudinally in a fillingwisedirection between selvages 12 and 13 at opposite ends of diaper blank10; a pair of elongate intermediate or pinning bar section or panels 14and 15 disposed on opposite sides of and interwoven with medial section11 and also extending between selvages 12 and 13; and a pair of elongatenon-raveling or pinking bar sections or panels 16 and 17 disposed onopposite sides of and interwoven with pinning bar sections 14, 15 anddefining opposite side edges of diaper blank 10.

Diaper blank 10 is formed of a fabric of interwoven sets of warp andfilling yarns and which is preferably of m'ulti-layer construction toprovide the desired absorbency and softness. In this respect, medialsection 11 is preferably formed of three layers of fabric 20, 21 and 22(FIG- URE 2) woven together at least at selvages 12 and 13 and atopposite sides of medial section 11 where the same is joined to pinningbar sections 14 and 15. Also, pinning bar sections 14 and 15 preferablycomprise two layers of fabric 23, 24 and 25, 26, respectively, thelayers of each pinning bar section being woven together at selvages 12and 13 and to one side of medial section 11 and to one of the pinkingbar sections 16 and 17. Pinking bar sections 16 and 17 are preferably ofsingle layer construction and have the outer side edges thereof pinkedto resist raveling.

Preferably, a band 27 of reinforcing warp yarns extends transversely ofthe central portion of diaper blank 10 and is interwoven with thesections thereof. Band 27 defines a fold area along which diaper blank10 is adapted to be folded to superpose opposite halves thereof and toform an elongate folded diaper 30 (FIGURE 3) which is preferably securedto this folded condition by spaced lines of longitudinally extendingstitching 31, 32.

It has been determined that the fabric forming diaper 30 can be woven insuch a manner and of such warp and/or filling yarns that the aforesaidcontour can be provided therein at no appreciable increase in the costof manufacture thereof over conventional non-contour diapers ofcomparable layer construction, and also without any decrease inabsorbency thereof, and without any material wrinkling or puckering ofthe fabric thereof. This contour is achieved by weaving the fabric sothat at least the fabric layers forming medial section 11 of diaper 30are shrinkable laterally of the diaper to reduce the width thereof andto drawn in opposite side edges thereof to impart a concaveconfiguration thereto. This shrinkability in at least the medial section11 of diaper 30 is preferably achieved by having at least those yarns,preferably the filling yarns, extending transversely of medial section11 of water-swellable cellulosic material such that the fabric includingthe same shrinks in the direction of these yarns upon being subjected toa conventional washing or laundering process, which is usually donebefore new diapers are used to enhance the softness thereof. Also, suchyarns, as originally woven into the fabric, have a high twist multiplewithin the range of 4.50 to 7.50 to enhance this shrinkability of thefabric. More preferably, these filling yarns are of cotton or high wetmodulus rayon and have a twist multiple within the range of about 5.50to about 6.75 for good shrinkage characteristics while still having goodabsorbency, softness and economic feasibility.

Preferably, all of the sections of diaper 30 are woven in the above setforth manner utilizing the same filling yarns throughout the diaper foreconomy in the manufacture thereof. Therefore, all sections of diaper 30are shrinkable laterally thereof, but medial section 11 is woven so asto have greater shrinkability than the remaining sections thereof. Thisgreater shrinkability in the layers of fabric in medial section 11 isprovided by each of these fabric layers 20, 21, 22, as originally woven,having less yarn interlacings per inch than each of the fabric layers23, 24, and 25, 26 of pinning bar sections 14 and 15, and the singlelayer of each of the pinking bar sections 16, 17, as originally woven.In addition, the pinning bar sections or panels are preferably wovenwith less yarn interlacings per inch than the pinking bar sections orpanels for greater shrinkability therein.

In a plain weave construction, which is preferred for all sections ofdiaper 30, an example of a fabric construction providing these variedyarn interlacings per inch in the various sections of the diaper wouldbe a fabric having a warp end count of 32 and filling pick count of 46in each of the layers 20, 21, 2,2 of medial section or panel 11; a warpend count of 48 and filling pick count of 32 in each of the layers 23,24, 25, 26 of the pinning bar sections or panels; and a warpend count of96 and filling pick count of 64 in each of the pinking bar sections orpanels 16, 17. It is noted that this fabric construction provides agreater total number of yarns in medial section 11 of the diaper than inthe remaining sections for providing greater absorbency therein, wherethe same is most needed. It should be understood that this fabricconstruction is one example only and many fabric constructions withinthe purview of the foregoing description may be used without departingfrom the scope of the present invention.

However, such a fabric construction having progressively increasinginterlacings per inch in the layers of fabric from the medial sectionoutwardly to the pinking bar sections is particularly preferred sincethe same not only provides medial section or panel 11 with greatershrinkability than pinning bar sections or panels 14, 15, but alsoprovides pinning bar sections or panels 14, 15 with greatershrinkability than pinking bar sections or panels 16, 17. Therefore,upon shrinking of diaper 30, a pronounced contour is provided therein,as is illustrated in FIGURE 4 which shows a diaper 30' in which theconcave configuration imparted to opposite sides edges is readily seen.

While not necessary, the wrap yarns in the fabric of diaper 30 are alsopreferably of cellulose material, such as cotton or high wet modulusrayon, for absorbency and economic reasons. However, these warp yarnshave a standard twist multiple providing lower twist therein than in thefilling yarns to provide a softer fabric. Further, to enhance thecontour effect imparted to diaper 30 upon washing thereof, the medialsection 11 preferably has a dimension longitudinally of the diaper nogreater than two-thirds of the overall length of the diaper. Thisassures that the greater shrinkage in the medial section of the diaperis provided in the portion thereof which will lie between the wearerslegs, which is the portion of the diaper wherein the width of materialis desired to be reduced, and avoids an undue or undesirable shorteningof the waist encircling portion of the diaper.

After originally weaving the fabric of diaper 30 in the manner set forthabove for providing the aforesaid contour therein, but before separatingthe same into diaper blanks 10, this fabric preferably is drawn warpwisethrough a caustic treating bath with no appreciable fillingwise tensiontherein. This caustic treatment increases the normal sinuosity of thefilling yarns in the fabric to a degree such that the fabric hassubstantial stretchability and a high degree of inherent recoverabilityin the fillingwise direction. It is noted that this stretchability maybe characterized as easy stretchability wherein a relatively small forcewill cause the fabric to stretch as compared with prior stretchablefabrics having elastomeric or rubber yarns therein, and also, thisinherent recoverability is also slower or easier than in such priorstretchable fabrics which is desirable for comfort to a wearer.

Therefore, diaper 30 formed therefrom has substantial lateralstretchability and recoverability which, for example, readily permitsdistention .and contraction of the badys abdomen without binding orbecoming undesirably loose and, hence, provides a better and morecomfortable fit for a wearer of the diaper. It is further to be notedthat the lateral shrinking of diaper 30 upon laundering thereof toimpart the aforesaid contour thereto, enhances the sinuosity of thefilling yarns, and hence, the lateral stretchability of the diaper, bycausing these yarns to recover from an elongated or stretched conditionif the same have not previously recovered therefrom.

Referring now to FIGURES 5-9 of the drawings, there is shown anotherform of diaper, generally indicated at 40, which is formed in similarmanner to diaper 30 to be shrinkable to provide the aforesaid contourtherein and to have substantial stretchability and recoverability forthe reasons set forth above. Diaper 40 differs from diaper 30 primarilyin the layer construction of the fabric and the manner of folding thesame to form the diaper. In this regard, a diaper blank 41 (FIGURE 5) isprovided which includes an elongate medial section or panel 42preferably extending longitudinally between selvages 43, 44; andelongate intermediate sections or panels 45, 46 on opposite sides of andinterwoven with the medial section 42 and likewise extending betweenselvages 43, 44.

As illustrated in FIGURES 7 and 8, medial section 42 is preferably oftwo-layer fabric construction throughout, and intermediate sections 45,46 are preferably of single layer construction throughout. Preferably, apair of spaced bands 47, 50 (FIGURE 5) of reinforcing Warp yarns extendtransversely of and are interwoven with the sections of diaper blank 41.Bands 47, 50 define fold areas along with diaper blank 41 is adapted tobe folded to form diaper 40, in which bands 47, 50 define reinforcedside edges and the medial and intermediate sections extend laterallybetween these reinforced side edges.

This folding of diaper blank 41 to form diaper 40 provides therein alongitudinally extending central portion which comprises threesuperposed two-layer portions 51, 52 and 53 (FIGURE 7) in medial section42 and three superimposed single layer portions, 54, 55 and 56 (FIG- URE8) in each of the intermediate sections 45, 46. Also, longitudinallyextending side portions of diaper 40 are provided on opposite sides ofthe aforementioned central portion and each comprises a pair ofsuperposed twolayer portions 60, 61 (FIGURE 7) in medial section 42, anda pair of superposed single layer portions 62, 63 (FIGURE 8) in each ofthe intermediate sections 45, 46. Diaper 40 is preferably secured inthis folded condition by spaced lines of stitching 64,65 extendinglongitudinally of and adjacent the sides of the central portion thereofand by overedge stitching 66, 67 across opposite ends thereof, whichoveredge stitching also prevent raveling and define non-raveling endsections.

As was the case with diaper 30, the fabric forming diaper 40 isoriginally woven to be shrinkable with greater shrinkability in medialsection 42 than in intermediate sections 45, 46 and non-raveling endsections 66, 67. The differential shrinkability is preferably providedin the same manner as in diaper 30 as described above and, hence, thisdescription will not be repeated. Also, diaper 40 has substantialstretchability and recoverability laterally thereof which is alsoprovided therein in the same manner as described above in connectionwith diaper 30. Therefore, when diaper 40 is laundered in conventionalmanner, the fabric thereof will shrink with medial section 42 shrinkinga greater amount later-ally of diaper 40 than intermediate sections 45,and 46 and non-raveling end sections 66, 67. This shrinkage isaccomplished without appreciable increased cost, without reduced theabsorbency thereof, and without material wrinkling or puckering of thefabric.

Such a shrunken diaper 40' is illustrated in FIGURE 9 and it is readilyapparent that the reinforced side edges 47', 50 thereof have a concaveconfiguration imparted thereto. As with diaper 30, medial section 42preferably has a dimension longitudinally of diaper 40 no greater thantwo-thirds of the-overall length of the diaper to enhance the contoureffect imparted thereto.

It will therefore be apparent that the present invention provides novelstretchable contour diapers having the desirable characteristics ofconventional non-contour diapers, but wherein the width of material inthe medial sections thereof is reduced without reducing the absorbencythereof, without material wrinkling or puckering of the fabric therein,and without materially increasing the cost of manufacture thereof.
